Definitions
- the invention relates to safety devices intended to recover skis in loose snow or deep snow, and in particular a device for preventing ski loss of the type comprising a strap connecting the skier's boot to a reel attached to the ski.
- ski stop consisting of a rod which is released when the skier takes off his shoes and which blocks the progress of the ski in the snow, has given the skier perfect autonomy.
- the "stop-ski” is nevertheless ineffective in powder snow.
- skiing has evolved a lot in recent years, and a skier who has reached a level which he considers extreme will still be attracted to off-piste skiing despite the prohibitions, dangers and safety advice.
- Another system used for recovering a loose ski consists of having a reel attached to the ski and connected to the skier's shoe by a strap which unwinds while keeping the ski attached to the skier's shoe in the event of a fall. of it.
- Such a system although effective, generally lacks flexibility and is not always reliable insofar as the belt can come off the reel in the event of a sudden fall, which can then lead to the loss of the ski.
- the object of the invention is therefore a device for avoiding the loss of ski boots in powdery or deep snow, of the type comprising a strap connecting the skier's boot to a rewinding means fixed to the sk, in which the reel is composed of two blocks integral with the ski connected by a main axis on which the belt is wound, each of the blocks comprising a spring of the spiral type whose movable end is integral with the axis, so that, when the skier takes off his shoes, the belt is held while keeping the ski connected to the skier's shoe at a certain distance from the latter.
- FIGS. 1a and 1b schematically represent the device of the invention mounted on the ski, the figure showing it the boot fixed to the ski, and FIG. 1b showing the boot separated from the ski
- FIG. 2 represents the base on which the two blocks making up the device of the invention are fixed
- FIG. 3 is a sectional view of the device the invention mounted on its base
- FIG. 4 represents the return spring used in each of the two blocks
- FIG. 5 is a sectional view of one of the two bearings supported by the winding axis of the belt
- FIG. 6 schematically represents the belt wound on its axis and leaving the orifice of the cover covering the device of the invention
- FIG. 7 represents a plan view of the housing integral with the boot of the skier in which the end of the strap is fixed
- FIG. 8 schematically represents the winding of the strap in the variant of the device according to the invention using two axes.
- Figures la and lb show the device intended to be mounted on the ski behind the heel, therefore below the center of gravity of the ski, in place figure la and barefoot ski figure lb.
- the base 1 shown in Figure 2 can be made of any rigid material such as a rigid plastic or a lightweight composite material. Rectangular in shape, it has at its ends two hollow locations 2 where the two blocks 3, preferably made of alloy, are positioned, and thus allowing the mechanism to be centered.
- Figure 3 shows the entire device. It is characterized by the two alloy blocks
- the recesses resulting from the drilling are provided with a slot 8 of approximately 0.8 mm thick and a height about 6mm intended to receive the fixed end 9a of the spring 6 and to fix it.
- the spring preferably used is of the flat spiral spring type, calibrated so as to give it a resistance capacity equal to approximately 3 kg. But it is obvious that any other spring or equivalent mechanism producing the same effect could be used.
- the two bearings 7 in FIG. 5 have central orifices 7a through which passes an axis 11 provided with a slot at each of its ends, with a thickness of approximately 0.25mm and a depth of approximately 6mm where is introduced the movable central tongue 9b (see Figure 4) of the spring 6.
- the axis 11 has a slot 11a in its center over a length of about 15mm for fixing the strap there.
- two rings 14 between which the belt is wound are crimped and are intended to push the two bearings into abutment against the springs and thus position the two alloy blocks at equal distance to be screwed on their base.
- the belt 13 leaves the cover 15 through the slot 16.
- the belt is provided at its end with a rod 17 made of rigid plastic or composite material, with a thickness of 4mm and a width of 20 to 24 mm, therefore wider than the slot 16, which allows it to stay outside and be used at will.
- the rod 17 located at the end of the belt 13 is intended to be placed in a small drawer-box 18 shown in FIG. 7 riveted to the rear of each ski boot.
- the rod 17 is positioned in the central opening of the housing 18 and is blocked by the drawer 20 which keeps the rod in abutment.
- the drawer 20 has a wider border than itself.
- two small pins (not shown) are provided inside the box in order to prevent it from coming out at the end of the stroke. The whole is molded in the factory to form a single piece.
- the cover 15 generally of semi-cylindrical shape, intended to ensure the protection of the device, can be made of rigid plastic or of composite material, forming only one piece with the base.
- the joint of these two elements is waterproof.
- the fixing can be carried out using simple screws on the sides after having previously perforated the two alloy blocks on their side, or by simple snap-fastening by concave and convex lugs molded respectively on the base and the housing.
- One of the peculiarities of the device according to the invention is to have a strap long enough so that in the event of the ski falling and loosening, the latter is moved away from the skier so that the latter is not injured by skiing if the fall is prolonged due to the slope. It is therefore necessary to provide a strap of 80cm or more. With an 80cm belt, the number of turns around the axis connecting the two blocks is about 15, which represents a diameter of 32mm when the belt is wound.
- the first axis 11 being, as in the device illustrated in the preceding figures, provided at its ends with a return spring and acts as a motor axis, while the second axis 12 acts only as a guide axis. Winding the belt on two axes allows the use of a good belt longer, for example 1.5m, while saving space on the height of the device relative to the base.
- the device of the invention makes it possible to distribute over two springs the sudden force which can take place during the fall of the skier. For the same desired tension force, it is therefore possible to have springs having half the tension and therefore obtain better flexibility of the assembly. This flexibility can prevent breakage of the belt attachment which could occur with the simple reels used previously.
- the force exerted by the belt when it takes place suddenly at the time of the fall is therefore balanced at all times on the two ends of the axis, which makes it possible to obtain great flexibility.
- the existence of two blocks, each having a spring considerably increases the reliability of the assembly insofar as, even in the event of one of the two springs breaking, the device will continue to operate thanks to the second spring.
